SPECIFICATION forming part of Letters Patent N0. 755,480, dated March 22, 1904:.

Application filed July 21, 1908.

To all whmn it may concern.-

Be it known that I, EDWIN M. GoLDsmTH, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Pencil Sharpeners, &c., of which thefollowing is a description.

My invention relates to point protectors for lead-pencils.

It comprises with such protectors pencilsharpening means and a cover for same which cannot be detached or lost.

It also consists of novel features of construction, all as will be hereinafter fully set forth.

Figure 1 represents an elevation of a protector embodying my invention. Fig. 2 represents, partly in section, partly in elevation, mydevice in its closed position. Fig. 3 represents in perspective the cutting portion of my device detached. Fig. 4 represents a cross-section through the line a m, Fig. 2. Fig. 5 represents a partial cross-section of a modification. Figs. 6 and 7 represent elevations in diiferent positions of a modified form of my device. Fig. 8 represents an elevation, partly broken away, of a portion of Fig. 7. Fig. 9 represents in perspective the modified cutting portion shown in Fig. 5.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings, 1 designates a tubular point-protector, consisting of a casing 2, slotted at 3 for the introduction of a pencil and having at its other end a socket 1 for the retention of an erasing-rubber 5. Intermediate of these tube portions is inserted a longitudinally-disposed blade 6 (shown in Figs. 1, 2, 3, and 4 of the drawings as secured in a tube portion 7 cut away to form end bands 8 and 9 and connecting-webs 10 and 11, one engaging the back of the blade 6 and the other parallel therewith.

I prefer to roughen the outer surface of the web 11 to form a file or abrading-surface, as shown in Fig. 1.

The bands 8 and 9 are firmly secured, as by soldering, in the adjacent ends of the portions 2 and 1. Sliding over one of these portions and adapted to be frictionally retained over Serial No. 166,433. on man the blade 6 is a sleeve 12. This is shown in Fig.v 1 in its open position abuttingagainst a .bead13 and in Fig. 2 in its closed position covering the cutting portion and held in place by a bead 14. It will be noted that end of the sleeve 12 is enlarged to pass over the bead 13, so that it may be used to protect the eraser 5 when the blade is in service.

In Figs. 5 and 9 I have shown the cut-away tube 7 and blade 6 as formed from an integral piece of metal, the side of the blade being roughened to. form an abrading surfa'ce.

In Figs. 6, 7 and 8 I have shown a bladecovering sleeve 15, having an aperture 16 adapted when in the position shownin Fig. 6 to expose the blade .6 and when in the position shown in Fig. 7 to cover the blade, the

aperture 16 registering with the web portion of the tube 2. A recess 17 of the end of the outer sleeve 15 forms shoulders 18 and 19, adapted to abut against a lug 20 on the protector-tube and maintain the outer sleeve in either of the positions shown. I have shown the lug 20 as a tongue thrown out from slot 21 on the protector portion. An inturned bead 22 engaging the other end of the sleeve prevents its longitudinal movement.

The operation of my device will be readily understood from the drawings and from the description already given. It will be seen that the portion 2 forms a convenient handle for the blade 6 in sharpening the pencil-point or like work, that the lead may be pointed on the file 11, that when covered by the outer sleeve the blade is fully protected from injury or from injuring anything on the desk or in the pocket, and that the sleeve itself can under no circumstances become detached and lost.

It is evident that various changes may be made by those skilled in the art which will come within the scope of my invention, and I do not, therefore, desire to be limited in every instance to theexact construction herein shown and described.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

' 1. A point-protector comprising a tube, a blade intermediate the ends of said tube, a sleeve movable on said tube and adapted to alternately cover and expose said blade and means for preventing the detachment of said sleeve from said tube.

2. A point-protector comprising a tube having pencil and eraser engaging ends, a blade intermediate said ends, a sleeve movable on said tube and adapted to alternately cover and expose said blade and means for preventing the detachment of said sleeve from said tube.

3. A point-protector comprising pencil and eraser engaging portions, a cut-away portion intermediate said engaging portions, a blade carried by said cut-away portion, a sleeve adapted to alternately cover and expose said blade and means on said tube portions for retaining said sleeve thereon.

4:. A point-protector comprising a tube, a blade and an abrading-surface intermediate the ends of said tube, a sleeve movable on said tube and adapted to alternately cover and expose said blade and means for preventing the detachment of said sleeve from said tube.

5. A point-protector comprising pencil and eraser engaging portions, a cut-away portion intermediate said engaging portions, a blade and an abrading-surface, carried by said cutaway portion, a sleeve adapted to alternately cover and expose said blade and means on said tube portions for retaining said sleeve thereon.-

G. A point-protector comprising a tube having a cut-away portion intermediate its length,

, a longitudinally-disposed blade secured in said tube adjacent said cut-away portion and a movable sleeve adapted to alternately cover and expose said blade.

7 Apoint-protector comprising a tube having a cut-away portion intermediate its length, a longitudinally-disposed blade secured in said tube adjacent said cut-away portion and at each end thereof and a movable sleeve adapted to alternately cover and expose saidv blade.

8. A point-protector comprising a tube having pencil and eraser engaging portions, a cut-away portion intermediate said engaging portion, a blade adjacent said cut-away portion and a sleeve longitudinally adjustable on said tube and adapted to alternately cover said blade and to extend beyond the eraser-engaging end of said tube.

9. A point-protector comprising tubular end portions and an intermediate portion consisting of end bands secured in the adjacent ends of said end portions and. a blade connecting said bands.

10. A point-protector comprising tubular end portions and an intermediate portion consisting of end bands secured in the adjacent ends of said end portions and a blade integral With and connecting said bands.
